使用WinApi和OpenGL的线程数量不足. [英] Extra, unaccounted for threads using WinApi with OpenGL.

问题描述

我的程序出现问题，使用Winapi的代码块会创建2个额外的线程.在所使用的函数的文档中，我什么都没有看到，这表明将创建线程.但是，如果我不运行此块，则我的程序只有1个线程，如果有，则有3个线程.这是代码块:

I have a problem in my program where 2 extra threads get created from a block of code that uses the winapi. I saw nothing in the documentation of the functions used that indicates that the threads would be created. But if I don''t run this block my program has 1 thread and if I do then it has 3. This is the code block:

if (!(hdc = GetDC(hwd))                           ||
    !(PixelFormat = ChoosePixelFormat(hdc, &pfd)) ||
    !(SetPixelFormat(hdc,PixelFormat, &pfd))      ||
    !(hrc = wglCreateContext(hdc)))
{
    DestructWindow();
    return false;
}

Is there any way to get rid of those 2 extra threads or are they supposed to be there?

推荐答案

James，

Microsoft GDI +库gdiplus.dll将在您的进程中产生工作线程.我认为没有任何记录的方法可以控制此情况.您可能可以通过下载 Process Explorer [ Windows调试工具 [

James,

The Microsoft GDI+ library gdiplus.dll will spawn worker threads within your process. I don''t think there is any documented way to control this. You can probably verify this by downloading Process Explorer[^] and right-clicking your process and selecting the ''Threads'' tab. If you have Debugging Tools for Windows[^] installed and your symbols properly setup you will even be able to inspect the call stack.
